Submission + - Malware Running on Graphics Cards

lcubo writes: Malware writers constantly seek new methods to obfus-
cate their code so as to evade detection by virus scanners.
Two code-armoring techniques that pose significant chal-
lenges to existing malicious-code detection and analysis
systems are unpacking and run-time polymorphism. In this
paper, we demonstrate how malware can increase its ro-
bustness against detection by taking advantage of the ubiq-
uitous Graphics Processing Unit. We have designed and
implemented unpacking and run-time polymorphism for a
GPU, and tested them using existing graphics hardware. We
also discuss how upcoming GPU features can be utilized to
build even more robust, evasive, and functional malware.

Submission + - Possible Hint to origin of Stuxnet Worm (cnbc.com)

Sooner Boomer writes: "There is a possible hint to the origin of the Stuxnet Worm which has been reported as running in the wild in Iran. Several of the teams of computer security researchers who have been dissecting the software found a text string that suggests that the attackers named their project Myrtus. The guava fruit is part of the Myrtus family, and one of the code modules is identified as Guava. FromTFA:

"Deep inside the computer worm that some specialists suspect is aimed at slowing Iran’s race for a nuclear weapon lies what could be a fleeting reference to the Book of Esther, the Old Testament tale in which the Jews pre-empt a Persian plot to destroy them. "


"Ralph Langner, a German computer security consultant who was the first independent expert to assert that the malware had been “weaponized” and designed to attack the Iranian centrifuge array, argues that the Stuxnet worm could have been brought into the Iranian nuclear complex by Russian contractors.

“It would be an absolute no-brainer to leave an infected USB stick near one of these guys,” he said, “and there would be more than a 50 percent chance of having him pick it up and infect his computer.”

So — put on your tinfoil hat (or yarmulke...), but watch out for unknown USB keys..."


Submission + - HP Names SAP Head As New CEO

An anonymous reader writes: Hewlett-Packard has picked Léo Apotheker, former head of German software giant SAP, to replace CEO Mark Hurd. Apotheker spent more than 20 years at SAP. During his tenure it became one of the largest business software companies in the world, and managed 18 consecutive quarters of double-digit software revenue growth between 2004 and 2009.

Submission + - 360-degree Holographic Display (engadget.com)

jshriverWVU writes: "Researchers at USC have taken another step towards that holiest of sci-fi dreams: the 3D holographic display. Using a spinning mirror covered with a "holographic diffuser," a special DVI implementation, and a high-speed projector, the team's device can project a three-dimensional image that can be viewed from 360 degrees — regardless of the viewer's height and distance. That's impressive, but that spinning mirror looks pretty dangerous. Check a video of the system in action after the break."

Submission + - Vermont Yankee License Delay (reformer.com)

mdsolar writes: "A review of an application to extend the Vermont Yankee nuclear power plant operating license by 20 years may be delayed after a collapse of a cooling tower at the plant last week. Entergy, the owner did not submit information about the collapsed tower in its application and the NRC is now requesting additional information to be included in its review. Additionally, there was an automatic scram at the plant yesterday. Was Murphy and optimist?"

Submission + - David Beckham - he's what's for dinosaur lunch (networkworld.com)

coondoggie writes: "If one existed today, a Tyrannosaurus Rex could chase down soccer star David Beckham and have him for a snack if he wanted to. That was the amusing conclusion of a new study out today that say while the monstrous T Rex, weighing some 6 tons was a fast runner, he by no means the fastest dinosaur out there as some popular lore would have it, still if he tripped, he'd likely die at that speed. The University of Manchester study used a supercomputer to calculate the running speeds of five meat-eating dinosaurs that varied in size from the smallest- about the size of a turkey, the 3kg Compsognathus to a 6 ton T Rex.The study puts the T Rex at speeds of up to 18mph, quicker than a professional athlete. The bipedal Compsognathus, by comparison, could reach speeds of almost 40mph — that's 5mph faster than the computer's estimate for the fastest living animal on two legs, the ostrich. A top human sprinter can reach a speed of about 25 mph. http://www.networkworld.com/community/node/18648"

Submission + - What's next for DVD? (computerworld.com)

Lucas123 writes: "As Blu-ray and HD DVD formats are at war with no clear victor in sight, DVD burners are getting cheaper and faster. Sony recently began shipping the latest iteration of its stand-alone DVD burner that's independent of a PC as well as a $70 internal and $110 external drive, and Pixela just released a $300 burner for the mobile camcorder user with its slick, slim-line design. So it begs the question, is DVD really headed for the scrap heap?"

Submission + - Putting your data center on an energy diet (computerworld.com)

jcatcw writes: There's more than one way to power a data center. Time Warner Cable is switching to modular UPS systems that scale in 20-kilowatt increments. Instead of setting up two large UPSs, they sets up five modules — three live and the other two on hot standby. Network Appliance is using a cogeneration system that combines a generator with a specialized chiller that turns the waste heat into a source of chilled water. It's powered by natural gas and can be used at peak summer hours when electricity charges are especially high. Belize Communication and Security in Belmopan, Belize, uses wind and solar to create enough battery power to run for two weeks before having to fire up generators. But there's also a lot more to energy savings than the power supply. The real costs are the equipment — generators, UPSs, PDUs, cabling and cooling systems. For a Tier 4 data center, which provides the highest level of redundancy and reliability, for every kilowatt used for processing, about $22,000 is spent on the power and cooling infrastructure. In such cases, there may be substantial gains from distributing air flow, using outside air or semi-liquid cooling, or doing computational fluid dynamics modeling. Some power management suggestions: adopt modular systems, install conduits that can handle expansion, be sure to analyze each component, and user wider racks.

Submission + - Content aware image resizing

hyperinactive writes: A Graphics technique, "Seam carving", for content aware image resizing. Keeps image details when shrinking images by removing image areas with lower significance. Useful in e.g. resizable webpages to keep proportions, or to smoothly remove unwanted details of an image.

Submission + - Linus on Linux (apcmag.com)

aerthling writes: APC Magazine has an interview with Linus about his kernel's versioning scheme, his view on the impact it has had, his personal hobbies, and most importantly, which distributions he runs at home.

Funnily enough, the only distributions I tend to refuse to touch are the "technical" ones, so I've never run Debian, because as far as I'm concerned, the whole and only point of a distribution is to make it easy to install (so that I can then get to the part I care about, namely the kernel), so Debian or one of the "compile everything by hand" ones simply weren't interesting to me.
